I guess parent comment is comparing facebook's quarterly revenue (~20 Billion) from ad sales, 50 million would be a fraction of a percent of 1 quarter of ad revenue I would imagine for a company like Facebook.
In the context of advertising, I read "57M" as $57,000. They would normally write 57MM if they meant $57 million, wouldn't they?

?? I would expect to see $57,000 abbreviated as $57K.
That's now how they roll in that business. CPM for instance = cost per thousand.
Maybe they all studied Latin or learned Roman numerals?
Yep, the 'M' means 'mille' as I understand it. 'MM' is 'mille mille', or 'thousand thousand.'
Do you mean like the Roman "M" for thousand and "MM" for million? That is mixing Arabic numerals with Roman numerals.
